I started reading a fic once and never finished it, so I'm hoping someone can link me to it. No clue who the author is or what it's called, but it's really original so I know someone will know it!
It's a future fic (or maybe an AU?) in which Brian and Justin go on a huge long roadtrip, but this fic isn't a fic exactly; it's told through pictures and maps and postcards and letters. Dozens and dozens of them. It's really cool :)
